An environmental change causes the

Biology
1 answer:
Feliz [49]4 years ago
5 0

Answer:

The correct option is<u> slight increase in salt concentration in the </u>

<u>environment.</u>

Explanation:

The main function of contractile vacuole in the body of a paramecium is to pump out excess water. But an increase in salt concentration in the environment will let the water move inside the cell by osmosis. Hence, the contractile vacuole will not perform its function and will not be able to regulate osmoregulation.

Other options are incorrect because slight changes in the temperature or pH won't affect the contractile vacuole and it will still be able to perform its function.

katrin [286]

Answer:

C. A phosphate group from ATP is added to a transport protein, changing its shape and facilitating transport.

Explanation:

ATP hydrolysis drives the active transport of substances through membrane proteins. During the process, the released phosphate group from ATP is added to the nucleotide-binding site present on the membrane protein to trigger a conformational change in it.

For example, the binding of a phosphate group from ATP to the nucleotide-binding site of NA-K+ ATPase brings about a conformational change in the protein. The phosphorylates pump has more affinity for K+ and lower affinity for Na+. It facilitates the release of bound Na+ from one side of the membrane to another.
